摘　　要：根据汽车转向及侧倾运动方程,并结合驾驶员视野和安全停车距离随车速变化的规律,建立了自适应前照灯系统(AFS)的实时三维控制模型,采用Matlab/Simulink设计仿真程序对其进行模拟,结果表明,根据车速、前轮转角、前后轮侧偏角、车身质心侧滑角和车身侧倾角来综合控制汽车在转向行驶时的前照灯照射距离及角度具有良好的响应。Because bad illumination on curves is important factor to cause traffic accident, in order to enhance illumination when a vehicle＇s turning, real time 3-dimension control model of adaptive frontlight system （AFS） for turning was put forward on the basis of vehicle＇ s turning and roll move equations, which also included changing discipline of a driver＇ s visual field and safety stop distance with velocity. The model could realize dynamic adjustment and accurate illumination of a vehicle＇ s light. Then it was simulated by virtue of Matlab/Simulink. The simulation result shows it is suitable to control illuminating distance and angle according to velocity, front wheel swing angle, font and rear wheel slip angle, body side-slip angle and roll angle, which supplies the foundation in theory for actual development of AFS.
